When materials are added to the surface of a ramp, which material will cause the OREO to roll the furthest?
Research
Making a Ramp
Materials: 1 board
3 books (1 inch?) Take the books and put them in a pile, then place board so it looks like a ramp and is a ramp. ScienceNetLinks (http://www.sciencenetlinks.com/lessons.cfm?DocID=21)
This helps me understand my project more because it tells me how to build a ramp. No other website that I could find had how to build a ramp! I needed to know how to build a ramp because I did not know how to and the OREOs need to go down a ramp.
Problem
When materials are added to the surface of a ramp, which material will cause the OREO to roll the furthest?
Hypothesis
I think that the water will make the OREO go the farthest because, like tires it might pick up speed and go further.
Materials
·spray bottle with water in it ·sand ·zout soap ·ruler ·recording sheet ·3 OREOs ·A few books that altogether equal 3 inches ·3 pieces of cardboard
Procedure
1. Get all the materials listed. 2. Make 1 ramp using the research above. 3. Spray it with water a few times then put one OREO down the ramp. 4. Change the board, and then put zout on it. 5. Repeat step 4 only this time put sand on the board. 6 .Record your data (which OREO rolled the farthest, 2nd farthest, etc.) on the recording sheet 7. Repeat steps 1-6 2 times 8. YOU ARE DONE!!!!!!!!!
My hypothesis was right because every time I did it, the OREO that was rolled down the ramp with water went the farthest.The second farthest was always the Zout.I didn’t expect that because it was sticky (I had sticky hands after the experiment!).The last one was always the sand, which I kind of expected because at first the sand OREO would not even go off the ramp!I realized that you needed to change the OREO every once in a while so that it would go down the ramp.Something I needed to put in my procedure was that you had to find a clear space to do the experiment because the OREOs kept hitting objects.Also, I had to tape the board to the books once.I forgot to put the part where you repeat 2 times in the procedure. Overall, I learned that if you want something to slide down a ramp, use water.
